Is the fairytale romance over for Mariah Carey and Nick Cannon? The superstar couple is reportedly calling it quits.

According to TMZ, the divorce is “a done deal.” Mariah and Nick separated back in May and are currently living apart. Divorce lawyers have been brought in to negotiate a property settlement and custody agreement for their twins.

The breakup was allegedly triggered after Nick’s appearance on “Big Boy’s Neighborhood” in March. Nick played Big Boy’s “Gimmie 5” game, where he had to reveal five celebrities he’s slept with. Nick named Selita Ebanks, Christina Milian, Nicole Scherzinger, and Kim Kardashian, the latter of which reportedly angered Mariah.

She was upset for weeks and felt humiliated, but the relationship never recovered.

To make things worse, Nick appeared on Howard Stern and talked about Mariah not having sex before their marriage, which set her off even more.

Mariah feels that Nick has abandoned her by taking every job offer when they don’t need the money, which has also kept him away from their kids.

Nick, on the other hand, feels that Mariah has become impossible because she surrounds herself with “yes men.” He says she can’t handle it when he disagrees with her.

E! News reports that the couple’s Bahamas home, where they wed in April 2008, and their Bel-Air estate are currently on the market.

The two have remained quiet, but Nick denied the divorce rumors during an interview with Parade in May.

“There’s no merit or truth to it,” he said. “It’s kind of humorous, really. It couldn’t be further off from the truth, and it really affects the credibility of the so-called newspapers.”

The couple celebrated their sixth wedding anniversary in April. They share three-year-old twins, Moroccan and Monroe.

UPDATE: Nick Cannon has confirmed that he and Mariah are living apart.

“There is trouble in paradise,” the “America’s Got Talent” host told “The Insider.” “We have been living in separate houses for a few months.”

But he shot down reports that the problems in his relationship are due to infidelity.

“My main focus is my kids,” he said of Dem Babies.

When asked for comment, Mariah’s publicist said, “I am not commenting on Mariah’s personal life, but Mariah is focusing on her children and her upcoming tour.”
